Hi this is my first post and I'm a total novice so bear with me please. I'm helping my neighbor with his 89 Astro and were stumped. He had the starter replaced and all the wiring involved double checked. It started great after that for about 6 times then nothing when he tried it the 7th time. Replaced the ignition switch after replacing the toggle switch previously put in. Still nothing. We have no clue where else to go at this point. He checked to make sure everything is getting juice where necessary but it still doesn't want to start. All the dash lights work when turning the key but that's as far as it goes.
